PV Fuse Holder is an abbreviation for Photovoltaic Fuse Holder, a base device specifically used in solar photovoltaic (PV) power generation systems to install and protect PV-specific fuses.
1. Core Function
Its main function is to secure the PV fuse and ensure a good electrical connection between the fuse and the circuit. When a PV array (solar panel string) experiences a short circuit or severe overload, the fuse will quickly melt, interrupting the fault current, thereby:
Protecting Equipment: Preventing fault current from burning out inverters, combiner boxes, or other expensive equipment.
Preventing Fires: Avoiding fires caused by overheating of the lines.
Isolating Faults: Safely isolating faulty solar panel strings in DC high-voltage environments.
